DISPLAY DEVICE, AND DRIVING METHOD OF DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To provide a display device in which a luminance irregularity generated in a display panel having lead-out electrode sections for cathode lines is suppressed as much as possible. SOLUTION: When EI elements 2 of a display panel 1 are made to emit light, voltage drops VR generated at transparent electrodes of cathode lines 4 are estimated by a voltage drop estimating section 22 of a display device 25 based on a number x of light emitting elements for every cathode line 4 while referring to image data. A pulse width computing section 23 sets the amount of supply of a driving current I to be supplied to the cathode side from the anode side by a pulse width PW based on the estimated voltage drops VR. A control signal generating section 24 supplies the driving current I having the amount of supply being set to driver ICs 8 and 9. To be concrete, as the estimated voltage drop VR become larger, the amount of supply of the driving current I is set greater in a time integral manner.
